| 摘要 |
The invention relates to a cooling-arrangement of an electrical machine. The electrical machine (G) is connected with a first cooling-system (CS11, CS21) for its direct cooling, while the first cooling-system (CS11, CS21) circulates a first cooling-medium (All, LQ11). The first cooling-system (CS11, CS21) is connected with a second cooling-system (CS12, CS22) to hand-over heat from the first cooling-system (CS11, CS21) to the second cooling-system (CS12, CS22). The second cooling-system (CS12, CS22) circulates a second cooling-medium (A12) to remove the received heat. The first cooling-system (CS11, CS21) is connected with a third cooling-system (CS13), which is a refrigeration-system, to additionally cool down the first cooling-medium (All, LQ11) of the first cooling-system (CS11, CS21).
